During a severe famine Isaac decides to migrate to Egypt God discourages him about that
KJV Genesis 26 : 1 - 2
And there was a famine in the land, besides the first famine that was in the days of Abraham. And Isaac went unto Abimelech king of the Philistines unto Gerar. 2 And the Lord appeared unto him, and said, Go not down into Egypt; dwell in the land which I shall tell thee of.
Years later during the time of Jacob similar conditions arise yet God actually encourages him to go to Egypt
KJV Genesis 46 : 3 - 4
And he said, I am God, the God of thy father: fear not to go down into Egypt; for I will there make of thee a great nation: 4 I will go down with thee into Egypt; and I will also surely bring thee up again: and Joseph shall put his hand upon thine eyes.
This paradox is slightly confusing on one hand God discourages the father to migrate to Egypt yet encourages the son to go there
Why did God reject Isaac's move to Egypt?
